Vehicle Technologies Office: EPAct Regulated Fleets

The Office of Energy Efficiency and Renewable Energy (EERE) manages several programs designed to fulfill the provisions of the Energy Policy Act of 1992 (EPAct), as amended, that regulate and guide certain fleets with the goals of reducing the United States’ petroleum consumption and increasing the availability of replacement fuels. Since 1992, regulated fleets have helped build a core market for alternative fuel vehicles (AFVs).

In fiscal year (FY) 2014 alone, federal, state, and alternative fuel provider fleets used more than 50 million gasoline gallon equivalents of alternative fuel. Learn more about U.S. alternative fuel vehicle data.

State and Alternative Fuel Provider Fleets

EERE's Vehicle Technologies Office (VTO) implements the State and Alternative Fuel Provider Fleet Program. This compliance program works with certain state government and alternative fuel provider (e.g., utility) fleets to reduce petroleum consumption and increase use of alternative fuels through the acquisition of AFVs as a percentage of their annual light-duty vehicle acquisitions, or employing other petroleum-reduction/alternative fuel deployment methods in lieu of acquiring AFVs.


Annually, covered fleets used Standard and Alternative Compliance options to exceed their aggregate AFV acquisition requirements. Learn more about annual state and alternative fuel provider fleet compliance with EPAct requirements.

Sustainable Federal Fleets

EERE's Federal Energy Management Program runs the Sustainable Federal Fleets program, which helps federal government fleets fulfill their petroleum reduction, alternative fuel use, and greenhouse gas emission requirements under EPAct and relevant executive orders. At least 75% of a federal fleet's covered light-duty vehicle acquisitions in U.S. metropolitan statistical areas must be alternative fuel vehicles, and fleets must make gains annually toward specific electric vehicle acquisition and GHG emission reduction targets.


Federal fleets consistently exceed their AFV acquisition requirements. Learn more about annual federal fleet performance relative to federal mandates.

Clean Cities

VTO also manages a voluntary alternative fuels and AFV program, Clean Cities, which supports local actions that alternative fuel stakeholders take to reduce petroleum consumption and increase alternative fuel deployment in transportation. Clean Cities brings together stakeholders in the public and private sectors to increase the use of alternative and renewable fuels and fuel efficiency measures that help both regulated and non-regulated entities minimize their use of petroleum. Private and local/regional government fleets are not subject to specific AFV acquisition or fuel use requirements, pursuant to EPAct.


In calendar year 2014, more than 643,000 of the AFVs on the road were deployed with help from Clean Cities efforts. Learn more about Clean Cities' goals and accomplishments.
